YARN-GUIDE.

I Patented Jan. 7, 1913.

To all whom it may concern:

Be it known that we, FRANK D. Hancock, and FEsrUs S. RAND, citizens ofthe United States, residing at Providence, in the county of Providenceand State of Rhode Island, have invented certain new and usefulImprovements in Yarn-Guides, of which the following is a specification.v

Our invention'relates to improvements in threador yarn-guides for use ontextile apparatus such as winding, spooling or other like machines.

Our invention is especially adapted for use with winding machines inwhich the yarn or thread leads to the thread-guide from above, and theobject of ourimprovement is to provide a device with means to retain theyarnin the guide and to allow easy and quick threading of the guide withthe use of one hand only. T

The invention is fully described in the following specification,illustrated by the accompanying drawings, in which Figure l is a frontelevation of a winding machine, showing our improved threadguide appliedthereto; Fig. 2, an enlarged elevation of the guide; Fig. 3, a sideelevas tion of the same; Figs. 4, 5 and 6, perspective views of the mainparts of the guide.

Referring first to Fig. 1, A designates the main frame of a windingmachine, of well known construction and B represents the traverse-framein which the threadguide- C is mounted: The thread-guide C is arrangedto reciprocate in a horizontal path back and forth along the face of thetube m on which the thread or yarn is wound, and as the cop or packageis built up thereon the traverse frame B swings back to allow the guidetoreoede from the.

in which t e winding is discontinued auto-.

matically upon the breakage or exhaustion of any one of the supply yarnsit is practically impossible to stop the machine'instantaneously and,therefore, vthe loose end is indentations (19 g'.

-guide holder E is bent f0rliable to be wound into the package if thesupply-cop is placed closely adjacent to the thread-gulde. To guardagainst this contingency, while at the same time economizing space, ithas been found advantageous to lead the yarn over a pulley or guidewheelplaced some distance above the machine.

As shown in Fig. 1, the yarn y leads from .the supply-cop (not hereillustrated) to the tension-device D, placed directly above it, andthence it is drawn up over the guidewheel and then down to thethread-guide C. When abroken yarn causes the machine to stop the end ofthe yarn cannot reach the thread-guide before the winding spindle ceasesto rotate and, therefore, the broken yarn can be easily-found, usuallybetween the guide-wheel d and the tension-device D, and the operator isenabled to repair the break or piece-up without delay.

It will be understood that with machines arranged as above described itis necessary to provide a thread-guide having means to retain the yarnin the guide-eye to prevent its pulling out from above and the preferredstructure of our device whereby we gain the advantages before mentionedwill now be described in detail.

Referring to Figs. 2 and 3, designates the guide-holder which ispreferably con: structed of sheet metal and adapted to be secured at itsbase to the reciprocating traverse-bar F, see Fig. 1. upper end of theguide-holder E is the thread-guide proper G shown in detail in Fig. 4.The guide G is preferably con- Secured to the structed of vitreousmaterial, such as por- I celain or glass, to adapt it to resist theabrasive action of the thread which drawsthrough its eye and as hereshown is formed substantially in the shape of a button. The

front face 9 of the gui e has a smooth,

-which serves asan eye for the yarn. The

opposite face of the guide G is molded with a central boss g flanked bytwo slots or The upper portion 6 of the threa ward from the main portionand struck-u or formed with a (circular depression e adapted to receivethe boss 9 of the guide 410 Secured to the back of the guide-holder E"is a thin, metal plate J formed with an upwardly extending portionterminating in the horizontally projecting arm or prong :5, see Fig. Q.Mounted on this prong j is an auxiliary guide-member K which acts toretain the yarn from drawing up out of the guide eye g. The auxiliaryguide K is also preferably constructed of porcelain or glass and isformed with a transverse hole 70 through which the prong j extends, thetwo members being secured together by filling the hole with cement orshellac. The guide K is also formed with a guide-eye 70 for the yarnwith a contracted opening 70 leading into the eye. Preferably the plateJ is formed with asmall lug or ear 9' which extends upward from the mainportion of the plate and abuts the end of the prong k of the member K.The ear 1' is provided to cover the joint between the bottom of themember K and the edge of the plate J and acts to direct the yarn up intothe eye is and to prevent it from catching in the crack between theguide K and plate J.

' Between the back of the guide-holder E and the plate J is secured abifurcated, wire loop-member L which acts as a threading guide to directthe yarn into the guideeyes of the members G and K. The loopmember L isformed with substantially parallel sides 1, Z, which are bent back inthe loops Z and Z ALF the sides Z, Z are bowed out to form an openingfor the screw it which projects from the back of the guideholder E andextends through a hole 7' in the plate J. A nut m is screwed on to theend of the screw 7:. and binds the plate J against the member L which,in turn is clamped tightly against the guide-member E. The loop Z of themember L extends some distance above the top of the auxiliary guide Kand is crooked over toward the loop Z The loop Z is bent in the formofwa shepherds crook with a rounded top reaching just above the top ofthe guide K.

It will be noted that the several parts of my improved guide are allsecured together by a single screw and, furthermore, the arrangement issuch that the guide'G is held firmly in place against side'playl This isof utmost importancesince the friction of the guide bearing against thesurface of the cop 1s liable to cause side strain as the guide isreciprocated at a high rate of speed and the present arrangementprevents it from working loose and becoming displaced. The

auxiliary. guide K preventstthe yarn from pulling-up out of theguide-notch g and the loop-member L provides for quick and easythreading of the guide as now described.

In practice the operator draws the yarn or yarns up from the tensiondevice and secures the ends to the tube on, or, in repairing a break inthe yarn the end is tied to the loose end on the package. The yarn isthen led up over the guide-pulley d and the portion 3 leading to thepackage is drawn into the thread-guide by a single movement of one hand.The operator simply gathers the several yarns over his fingers and drawsthem across the rounded top of the guiding loop Z against the loop Z.The loop I deflects the yarns down back of the auxiliary guide-member Kand upon reaching the bottom of the rounded rong k they will enter theopening into t e guide-eye 7c. The guiding of the yarns into the eye 7cserves also to seat them in the notch g of the guide G so that they willlead therefrom directly on to the surface of the package andconsequently the coils of winding are accurately controlled during thereciprocation of the guide. 7

It will be observed that our improved guide can be threaded with easeand des-, patch without particular care or skill onthe part of theoperator; and, furthermore, only one hand is required for threading itso that the other can be employed in starting the machine throughmanipulation of the starting lever usually provided.-

It will be obvious that various modifications might be made in thestructure and arrangement of the parts of our new device withoutdeparting from the spirit or scope of the invention.
